Performance Analysis
The FP16 dense performance of 989 TFLOPS on the H100 exceeds the 40.6 TFLOPS on the RTX 3070 by a significant margin. This delta indicates that the H100 handles larger batch sizes during training and inference operations more effectively than the RTX 3070. Memory bandwidth of 3350 GB per second on the H100 supports higher throughput compared to 448 GB per second on the RTX 3070. When comparing dense FP16 figures the H100 delivers superior results to the RTX 3070. The same holds for FP16 with sparsity where the H100 reaches 1979 TFLOPS against 81.3 TFLOPS on the RTX 3070. Such differences translate to faster processing times for matrix operations in both dense and sparsity modes.

When to Choose the H100
For workloads requiring 80 to 94 GB VRAM the H100 serves as the appropriate selection. Its 3350 GB per second bandwidth and 989 TFLOPS FP16 dense performance enable handling of extensive models that exceed the capabilities of the RTX 3070 with its 8 GB VRAM.
When to Choose the RTX 3070
The RTX 3070 with its 220 W TDP fits environments where power efficiency matters more than peak performance. Its 40.6 TFLOPS FP16 dense rating suffices for smaller scale tasks that do not demand the 700 W consumption of the H100.
Use Cases
The H100 supplies 989 TFLOPS FP16 dense performance and 80 to 94 GB VRAM which support large model training beyond the 40.6 TFLOPS and 8 GB on the RTX 3070.
The H100 delivers 989 TFLOPS FP16 dense performance and 3350 GB per second bandwidth for efficient inference at scales not possible with the RTX 3070 40.6 TFLOPS and 448 GB per second.
The H100 provides 1979 TFLOPS FP16 with sparsity and 80 to 94 GB VRAM to accommodate fine tuning of sizable models unlike the RTX 3070 with 81.3 TFLOPS and 8 GB.
The RTX 3070 operates at a 220 W TDP with 40.6 TFLOPS FP16 dense performance for local generation tasks that align with its 8 GB VRAM capacity.
The H100 achieves 67 TFLOPS FP32 and 3350 GB per second bandwidth to accelerate scientific simulations beyond the RTX 3070 20.3 TFLOPS and 448 GB per second.
